Cetuximab With Radiotherapy for Locally Advanced Squamous Cell Carcinoma of the Head and Neck in Chinese Subjects

Phase 3
Completed
Conditions
Squamous Cell Carcinoma of the Head and Neck
Interventions
Biological: Cetuximab + concomitant boost radiotherapy
Registration Number
NCT01012258
Lead Sponsor
Merck KGaA, Darmstadt, Germany
Brief Summary

Primary objective: to assess the antitumor activity and safety profile of cetuximab when given in combination with radiotherapy (RT) for the treatment of locally advanced squamous cell carcinoma of the head and neck (SCCHN) in Chinese subjects.

Secondary objective: to assess the pharmacokinetic (PK) profile and immunogenicity of cetuximab in Chinese subjects.

Further objective: to identify for cetuximab potential predictive biomarkers of response and safety.

GroupInterventionDescription
CetuximabCetuximab + concomitant boost radiotherapyAll eligible subjects will receive cetuximab treatment only during week 1 of the treatment course and concomitant cetuximab and boost radiotherapy (RT) during week two to week seven of the treatment course
Primary Outcome Measures
NameTimeMethod
Best Overall Response (BOR)Baseline until the date of first documented progression or discontinuation from the study due to any cause, assessed every 3 months following the 8 weeks after the end of RT visit until the end of trial (EOT) visit

Best overall (objective) response was defined as the occurrence of complete response (CR) or partial response (PR) based on the investigator's assessment according to modified World Health Organization (WHO) criteria confirmed at a repeat assessment performed no less than 28 days after the criteria for response were first met. CR was defined as disappearance of all index lesions. PR was defined as a 50% or more decrease in the sum of the products of diameters (SOPD) of index lesions compared to the baseline SOPD, with no evidence of PD.

Secondary Outcome Measures
NameTimeMethod
Progression-Free Survival (PFS)Baseline up to disease progression or withdrawal or 12 weeks after the last radiotherapy of the last participant

Progression-free survival was defined as the duration (in months) from first administration of trial treatment to first observation of PD (radiological or clinical, if radiological PD is not available), or death due to any cause. The PFS time of participants without observation of PD but death occurring after two or more missed consecutive tumor assessments (i.e. two-fold scheduled time interval of two consecutive tumor assessments) was censored on the date of last tumor assessment or first administration of trial treatment (whichever was later).
